Formula:

The electrostatic force (F) between two point charges (q1, q2) separated by a distance (r) is given by Coulomb's Law:

F = k * |q1 * q2| / r2

  • F = Electrostatic Force (Newtons, N)
  • k = Coulomb's Constant ≈ 8.9875 × 109 N·m2/C2 (in vacuum/air)
  • q1 = Magnitude of the first charge (Coulombs, C)
  • q2 = Magnitude of the second charge (Coulombs, C)
  • r = Distance between the two charges (meters, m)
